For now there is many things to do They added a Survival mode, Freeroam mode (In this mode you can go all around the city and join at teams like the Bandits and the Army), Fortress Mode (In this mode you have to protect your leader from the incoming waves of zombies, every 5 waves the special zombies comes out!) and Exploration Mode (This mode is similar to freeroam but you have more things to do, and also you can do your own fottress by 0% and get gascan for your cars and those realistic things :P)
